Complex Multi-Step Problems
Make sense of complex multi-step problems involving large numbers, fractions, decimals, and percentages by analysing what is known and unknown, planning multi-step strategies, and evaluating reasonableness through estimation and inverse operations
Lesson
Set out your lesson
“Complex Multi-Step Problems means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Paper strips or a folded circle
- Pencil and labels (1/2, 1/4)
Extra for the adult
Worked example. Fold a strip in half: each piece is 1/2 of the whole.
Optional challenge. For Complex Multi-Step Problems, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Complex Multi-Step Problems, not mastery.

Check understanding
- Break a three-step problem involving unit conversion and multiplication into sub-problems and solve systematically
- Estimate 4,832 × 7 as roughly 5,000 × 7 = 35,000 to check a calculated answer of 33,824
- Identify that a percentage answer over 100% doesn't make sense in context
“When your child faces a complex multi-step maths problem involving percentages, large numbers, or fractions, do they pause to identify what's known, estimate an answer, and then check their final result makes sense?”
